Abstract

Ridge gourd (Luffa acutangula) is a climbing vegetable that produces edible fruits. Young fruits are harvested when the cotyledons have not yet formed. This study covered morphological characteristics, growth behavior, and cultivation practices suitable for increasing the production of the ridge gourd in the urban ecosystem. Results of observation revealed the heart-shape leaf of the ridge gourd was very uniform and the leaf surface was flat so that their leaf area could be accurately estimated using leaf length and/or width (R2 > 0.97), yet leaf thickness was not a reliable predictor for the leaf area (R2 < 0.34). The length of the petioles was not correlated with the leaf blade area. Single leaves, multiple tendrils, bunches of male flowers and/or single female flowers, and one branch could be formed at each stem node. Water content in leaf blade was lower than in the petiole. This phenomenon is related to water favor loss due to transpiration activity. Nevertheless, the total conserved water within the leaf blade was 6.26 times more than that within the petiole. The process of fruit enlargement followed the Sigmoid curve. The upper-end curve flattened 10 days after the female flower bloomed. Moreover, at 10 days, cotyledon has not yet formed. Based on the leaf SPAD value, by time the fruit began to enlarge, 4-5 leaves at the stem base were instigated to show symptoms of senescence. Ridge gourd fruit fresh weight can be best estimated using the length x diameter as the predictor.

Abstract

Aglaonema commutatum or aglaonema is an ornamental leaf plant. In Indonesia, it is populary referred to as Sri Rejeki. Aglaonema variety Lady Gaga has high aesthetic value and demand by many people because its distinctive patterns and colors. The success of aglaonema cultivation is influenced by the composition of growing medium used. This study aims to determine the best planting medium composition through a comparative study. The research was conducted from July to September 2023 in Palembang City. Was arranged based on Randomized Block Design, consisting of three treatments: volcanic sand (M0), volcanic and rice husk 1:1 v/v (M1), and volcanic sand and risk husk 1:2 v/v (M2). The research data were analyzed using Analysis of Variance (ANOVA). The result of this study showed that the use volcanic and rice husk 1:1 v/v (M1) significantly enhanced all growth parameters, including the number of leaves, leaf length, leaf width, and new leaf growth; and parameters related to visual color and quality grade, namely parameters color, brightness, shape and size, also aglaonema leaf motif. In addition, direct sunlight also effect the color, brightness, and leaf motif of aglaonema var. Lady Gaga which is increasingly fading. Therefore, it is recommended that aglaonema cultivation be carried out in shaded areas that not exposed to direct sunlight.
